Now, list down the factors of 212
:1,2,4,53,106,212
Now, list down the factors of 249
:1,3,83,249
Greatest Common Factor
We found the factors 212,249 . The biggest common factor number is the GCF number.
So the greatest common factor 212,249 is 1.
Lets's calculate LCM of 921,355
Given numbers has no common factors except 1. So, there LCM is their product i.e 326955
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/326955
Therefore, the GCF of Fractions 212/921,249/355 is 1/326955
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 921,355 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(921,355) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(921,355) x common factors =1 x 1 = 1
LCM(921,355) = ( 921 × 355 ) / 1
LCM(921,355) = 326955 / 1
LCM(921,355) = 326955
